Django: The value of the id field is coming None
I want to create a unique id for all my groups in my django project which will help us to easily detect the user action. I have tried the following: Models: class Group1(models.Model): urlhash = models.CharField(max_length=6, null=True, blank=True, unique=True) user = models.ForeignKey(settings.AUTH_USER_MODEL,on_delete=models.CASCADE,null=True,blank=True) group_name = models.CharField(max_length=32) This is the functionality I have given: def save(self): if not self.urlhash: if self.user.profile.user_type == 'Bussiness User': self.urlhash = 'B' + str(self.User.id) + ('00') + str(self.id) else: self.urlhash = 'P' + str(self.User.id) + ('00') + str(self.id) super(Group1, self).save() But str(self.id) is coming None. Can anyone plz explain me why this error is happening? Thank you -
Django crontab not workong in backgroung
I am using django-crontab to run some cron jobs as part of my project. I have a virtual environment setup for this particular project. So after activating the environment, I add the jobs by using the following command : python manage.py crontab add I see that my jobs are succcessfully added to the OS crontab, however when I see the logs, I found that it was not able to find certain modules(read all) that were installed in virtual environment. However if I run those crons manually by passing the hash to the run command it runs successfully. On further inspection I found when the crons are added to the crontab, the python binaries are pointed to the global(system level binaries) instead of the virtual level binaries. The only soulution I can think of is to run pip instal at a system levwl but that will mess up the sanbox environment I intend to create. Any ideas? -

How to access attribute elements from a JSON file on a Django Template?

How to view a shopping cart on each page without a context processor?
I have a simple django eCommerce application that has shopping cart functionality. I am trying to extend my application so that I can see the contents of my shopping cart no matter what page of the application I am on. I was following this tutorial, which states I should use a context processor to do this functionality. However, when attempting to do so, I was not having luck getting this to work. I asked a question showing my approach, and someone commented I should not be using a context processor and there is no need as my cart is being returned from the view. OK. My question is, if the tutorial is wrong why is it wrong, and if a context processor is not needed, why am I unable to display data from my shopping cart in each page when just using views? The relevant section of my template where I want to show the total price of my shopping cart: <div class="header-cart-total"> Total: {{ cart.get_total_price }} </div> This works on the page for the actual cart itself, and I believe I am passing the correct views. How can I troubleshoot this? -

I want to serialize a python object, after saved it into mysql(based on Django ORM) I want to get it and pass this object to a function which need this kind of object as a param. Following two parts are my main logic code: 1 save param part : class Param(object): def __init__(self, name=None, targeting=None, start_time=None, end_time=None): self.name = name self.targeting = targeting self.start_time = start_time self.end_time = end_time #... param = Param() param.name = "name1" param.targeting= "targeting1" task_param = { "task_id":task_id, # string "user_name":user_name, # string "param":param, # Param object "save_param":save_param_dict, # dictionary "access_token":access_token, # string "account_id": account_id, # string "page_id": page_id, # string "task_name":"sync_create_ad" # string } class SyncTaskList(models.Model): task_id = models.CharField(max_length=128, blank=True, null=True) ad_name = models.CharField(max_length=128, blank=True, null=True) user_name = models.CharField(max_length=128, blank=True, null=True) task_status = models.SmallIntegerField(blank=True, null=True) task_fail_reason = models.CharField(max_length=255, blank=True, null=True) task_name = models.CharField(max_length=128, blank=True, null=True) start_time = models.DateTimeField() end_time = models.DateTimeField(blank=True, null=True) task_param = models.TextField(blank=True, null=True) class Meta: managed = False db_table = 'sync_task_list' SyncTaskList( task_id=task_id, ad_name=param.name, user_name=user_name, task_status=0, task_param = task_param, ).save() 2 use param part def add_param(param, access_token): pass task_list = SyncTaskList.objects.filter(task_status=0) for task in task_list: task_param = json.loads(task.task_param) add_param(task_param["param"], task_param["access_token"]) # pass param object to function add_param If I directly use Django … -
Why does adding a Django redirect stop database from populating?
So, long story short, I have been having issues implementing Django CreateViews. I am very close to getting this to work, but a new issue has suddenly arisen. Without the redirect in the following code, my database populates new Model instances. However, after adding the redirect to the success page, I cannot see new model instances in my database or in the Django admin page. Apologies in advance if I'm missing something simple. I can post more code if necessary but my guess is that it's going to be something in either views.py or my template views.py class SuccessView(TemplateView): template_name = "success.html" class DeviceChoiceView(CreateView): model = DeviceChoice form_class = DeviceChoiceForm success_url = 'success.html' template_name = 'index.html' ## All the code below this point is what stops the database from populating ## def form_valid(self,form): return HttpResponseRedirect(self.get_success_url()) def get_success_url(self): return ('success') index.html <!DOCTYPE html> <html> <head> <title>Port Reset</title> </head> <body> <h1>Device Database</h1> <form action="" method="post"> {% csrf_token %} {{ form.as_p }} <input type="submit" id="deviceSelection" value="Submit"> </form> </body> -
